Dr. Bayer is an excellent and outstanding Endocrinologist. I have been seeing him for over 20 years. He's very thorough and explains things to you. He takes his time and listens to you. He's very friendly and he has a great sense of humor. He's the best Endocrinologist around and I would recommend him to anyone!!! ?

Dr. Bayer has always listened to my symptoms, not just bloodwork results. When the tests he ran came back normal, but my symtpoms said otherwise, he ran more tests until he figured out what was wrong. When my prognosis wasn't great, he personally called me to go over the results and then followed up with a second phone call a week later to see if I had any new questions since our first conversation.

Dr. Bayer is a Diabetic Endocrinologist that I have complete trust in has really turned my A1C Goal/Goals to the Positive. He is very knowledgeable in his field and he always spends appropriate time w/patient/patients. I will be 62 in December and have been battling Diabetes since 1999/2000. He has also been a big influence on how I feel about my condition-always Positive.

Dr Bayer is a no-nonsense doctor that is very knowledgable and thoruough. I have gone to him for many years before a car accident and am now able to see him again. I could not find his phone number so I looked it up. As I read the reveiws that were positive, I could relate. As I read the negative reviews I wondered what could have gone wrong. I made my appointment a little concerned. Well, I can only say that Dr. Bayer is still the caring wonderful doctor that I remember.

He needs to retire. He's clearly mad at everything, he was 30 minutes late to an 8:00 am meeting and told me out of the gate he already didn't know what to do. He took no time to listen and understand. he's terrible, go somewhere else

One of the worst doctors I have ever seen. Rude, disrespectful, and just plain mean. He doesn't care about patients and this was shown by his horrible bedside manner. He needs training on how to be nice to people.

Dr. Bayer is so nice. He listens and is excited when he sees me progressing in my health. Worked consistently to get my thyroid medication to the appropriate level.

Rude bedside manner, rushes through, and was annoyed when I had to mention multiple health issues. He really seems to hate his job. Probably competent with thyroid issues but just too rude and unhappy!

Dr Bayer acted like a robot.
Dr Bayer made eye contact 5 seconds during the entire appointment. He spent all his time filling out forms on his computer instead of listening to any concerns I had.
His bedside manner is horrible, he is extremely unwilling to entertain other professional opinions. He was very concerned about if insurance will cover instead of the care of the patient, save yourself the frustration find a different doctor who cares about your health & issues.
